HAULING rruaiv'r.

Application filed February 21, 1914.

To all whom it may concern:

Be it known that I, ANTON GonAN, a subject of the German Emperor, and resident of Kattowitz, Germany, have invented certain new and useful Improvements in Hauling Plants, of which the following is aspecification.

his invention relates to improvements in hauling plants, and its object is to provide suitable means for safely controlling the speed of trucks running on inclined planes and for preventing the trucks from being stopped by small obstacles placed on the rails, the hitherto used connecting-ropes and coupling of the trucks being entirely dispensed with.

The accompanying drawing shows the subject matter of the invention.

Figure 1 is a side view of the improved plant, and Fig. 2 a fragmentary plan view of the same.

Two ropes or chains 1 running beside each other in parallel directions are provided above the track for the mine trucks and connected by cross-bolts 2, the latter being arranged at such uniform distances from each other as correspond to the length of the trucks used but with a small play of about 5 centimeters. The hauling element thus produced is, with self-acting inclined planes, endless and at both ends of the inclined plane led over horizontal rollers 4t, 5 above the rails for the trucks. The position of height of the drums is so determined that the trucks at the head of the inclined plane can easily run underneath the drum there located into the space between each two cross-bolts, while at the bottom end of the inclined plane the trucks can again freely run beneath the drum there located. Fig. 2 shows in a plan view how a truck 3 is guided in a space between two cross-bolts, the front wall of the truck bearing firmly against the corresponding cross-bolt 2 in order to be thus led down the inclined plane in a com- Specification of Letters Patent.

pletely safe way. The improved hauling plant acts thus like a kind of moving barrier, which prevents the trucks from unintentionally running down the inclined plane at dangerous speed. Besides, the improved hauling plant acts by the rear cross-bolts to push the trucks forward when they are accidentally stopped by small obstacles on the rails, for instance a small piece of coal or the like, such obstacles being thus simply overrun by the truck. The upper non-acting part of the endless hauling plant must, of course, be suitably supported by rollers, in order not to hang through and thus to disturb the working of the trucks. Of course, the improved hauling plant can also be used for horizontal planes.

What I claim, is:

1. In a hauling plant for use in connection with mine trucks, in combination, two fleXible elements arranged parallel to one an other above the track for the mine trucks, and cross-bolts to connect said flexible ele ments uniformly distributed over the whole length of the latter and adapted to engage a Whole mine truck between each two of them and thus to completely surround the truck from above, substantially as and for the purpose set forth.
